Related terms for steel pipes

Related terms for steel pipes 1. Size (1) Nominal size: It is the nominal size stipulated in the standard, the ideal size desired by users and manufacturers, and the order size specified in the contract (2) Actual size: It is the actual size obtained during the production process, which is often larger or smaller than the nominal size. This phenomenon of being larger or smaller than the nominal size is called deviation. (3) Meter

Types of OCTG casing

Types of OCTG casing OCTG casing is a steel pipe used to support the wall of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well uses several layers of casing according to different drilling depths and geological conditions. Cement is used to cement the well after the casing is run down. It is different from tubing and drill

What are the mechanical properties of seamless steel pipes?

What are the mechanical properties of seamless steel pipes? Mechanical properties are important indicators to ensure the final performance of seamless steel pipes, which depend on the chemical composition and heat treatment system of the steel. In the seamless steel pipe standard, the tensile properties (tensile strength, yield strength and yield point, elongation), hardness, toughness index, high and low temperature properties required by users are specified according to different usage requirements.

In this article, we will delve into the basics of hydraulic tubing and piping, exploring their functions, materials, design

The Differences Between ERW and Seamless Steel Pipes

The Differences Between ERW pipes(https://www.eastern-steels.com/products/erw-steel-pipe.html) and Seamless Steel Pipes(https://www.eastern-steels.com/products/carbon-steel-seamless-line-pipe.html) Steel pipes are used in a wide range of applications, from oil and gas pipelines to structural steel and more. Two of the most common types of steel pipes are ERW pipes and seamless pipes. While both types of pipes are made from high-quality steel, there are some significant differences between the two. In this article, we will explore the differences between

Seamless casing pipe vs ERW casing pipe

Seamless steel casing pipes-casing made of seamless steel pipe as raw material Seamless pipe refers to a steel pipe manufactured by four methods: hot rolling, cold rolling, hot drawing, and cold drawing. There is no weld seam on the pipe body itself. ERW casing pipe-casing made of electric welded pipe as raw material ERW pipe refers to a straight seam welded pipe manufactured through a high-frequency resistance welding process. The raw material steel

Anti-corrosion technical requirements for seamless pipes

Seamless steel pipe (SMLS) is the most widely used pipe material at present. Generally, it needs anti-corrosion treatment when it is used for chemical pipelines, oil pipelines, natural gas pipelines, water pipelines and other projects. The common anti-corrosion processes of seamless steel pipes mainly include 3PE anti-corrosion, Epoxy coal tar anticorrosion, epoxy resin anticorrosion, IPN8710 anticorrosion, cement mortar anticorrosion technology, etc. 1. Why is seamless steel pipe anti-corrosion? Seamless steel pipe is

What are the commonly used heat treatment processes for seamless steel pipes?

There are many varieties of steel pipes, and the steel grades (species) used are not the same. The chemical composition of the same variety of steel pipes may also be different, but after heat treatment, the steel pipes can meet the relevant technical standards or technical conditions of the purchaser. According to product standards, seamless steel pipe heat treatment processes mainly include the following five categories. (1) Quenching + high temperature

Technical Standards for Precision Seamless Hydraulic Tubes

What is precision hydraulic seamless steel tube? Precision seamless hydraulic tube made of precision cold drawn seamless steel tubes that are processed by black or gray phosphating process, and the phosphated steel tubes are sealed and rust-proofed.Hydraulic steel pipes are basically divided into fluid pipes and oil steel bobbins used in hydraulic systems, also known as honing pipes, and cold-drawn or cold-rolled precision seamless steel tubes also include hydraulic steel tube.
